Never seen a flight simulator cabin close up? The servos in those move a
substantial weight very quickly and precisely.

I'm sure the mechanical side its simple , I'm wondering how they keep an
accurate lock on the satellite however. Does it actively scan for the signal
or does it take readings from the planes GPS & gyroscopes and work out
where it should be?

Read up about the Boeing system, I know that works. It's also $500k to
install per plane, so not a child's toy.
